Re: Cut the sh*t!
Your observation about the location of measuring points may be accurate but you may be failing to draw the correct conclusion from it.
Increasing urbanisation (and destruction of forests etc.) is part of the problem, so there is no reason to exclude that data. Increasing population is also a factor. So the climate is probably getting warmer because we are emitting more CO2 because there are more of us in more developed situations which tends to degrade the things that mitigate CO2 in the atmosphere. The population people say the growth in numbers will slow down IF, especially, life-expectancy for children continues to improve. But will that happen if the climate continues to get hotter? That's the flip side to the economic development argument. Reducing CO2 is unlikely to create an economic disaster, it hasn't so far where it's been done, it just creates new industries (wind, solar etc.).
